''Bart vs. The Space Mutants'' is the first LicensedGame for the NintendoEntertainmentSystem (also ported to the SegaMasterSystem, GameGear, SegaGenesis and numerous computers) based off ''WesternAnimation/TheSimpsons'', developed by [[Creator/AbsoluteEntertainment Imagineering]]. The game revolves around Bart attempting to foil the space mutant's plan to power their world-conquering machine by collecting random objects.

Followed by ''VideoGame/TheSimpsonsBartVsTheWorld''.
!!This game provides examples of:
* AmusementPark: The third level.
* BossRemix: [[PlayingWithATrope Sort of]] - the three boss themes are simply parts of the main theme repeated over and over. [[MostAnnoyingSound It gets really annoying after a while.]]
* CassandraTruth: [[AllThereInTheManual According to the manual]], the reason Bart has to collect letters to get assistance in the {{Boss Battle}}s is because he's trying to get evidence to subvert this.
* CollectionSidequest: The evidence.
* DepthPerplexion: In certain places, you can stand on the horizon or "walk" along a river by jumping on the background. The game is highly inconsistent with this, even within the same screen. [[note]]It's really a 2D game with invisible platforms, flying enemies and backgrounds indistinguishable from the floor. The graphics do a good job at simulating depth though.[[/note]]
* EasilyThwartedAlienInvasion: More or less lampshaded in the game. The aliens have a machine that can run on anything, but never think to fuel it with something already in abundance; instead they choose purple objects, or hats.
* EasterEgg: By firing a rocket at the "E" in the Kwik-E-Mart's sign, you get both an extra life and the game's SoundTest! Unfortunately, it only plays sound effects.
* EverythingTryingToKillYou: Including ''shoes'' and walking ''shopping bags''.
* GracefulLoser: The aliens prove to be this in the ending.
* MiniBoss: The alien man in the second level.
* NintendoHard: Bart can only take two hits before dying, and for the most part he has absolutely no way to actually fight the enemies.
* PassThroughTheRings: Near the end of the second level.
* PowerUpMount: Inverted - the second time you see the RecurringBoss, he rides a giant shoe.
* RecurringBoss: Again, the alien man in the second level.
* RushmoreRefacement: Complete the game, and the space mutants add Bart's face to honor their WorthyOpponent.
* ShoutOut: Bart's x-ray glasses are generally considered a reference to ''Film/TheyLive''.
* SlidingScaleOfCollectibleTracking: This game uses "It's Here Somewhere".
* SmashingHallwayTrapsOfDoom: The second level has giant shoes which act as these.
* SomeDexterityRequired: The control in this game is '''dreadful'''. Bart cannot and will not [[JumpPhysics execute a proper running-jump]]. As a consequence, simple platform sections and obstacles become ''[[PlatformHell nightmarishly difficult]]'' to overcome.
* SoundTest: See EasterEgg.
* SummonMagic: You can summon Grandpa to give you coins with a whistle... providing you stand one exact spot in the first level. Otherwise you'll just summon a dog to attack you.
** Using a donut in the last level summons Homer to act as a SmartBomb.
* SymbolSwearing: In the cutscene before the third level.
* TacticalSuicideBoss: The second boss drops suitcases, which you need to jump on in order to damage
* TotallyRadical: The box.
* UnwinnableByMistake: It's almost impossible to clear the Museum without losing a life due to a section with very slow disappearing reappearing platforms that eats about 300 seconds off the timer.
